To aZZ whom. it may concern.-

Be it known that I, AMOS SHEPARD, a citizen of the United States, residing at Plantsville, in the county of' Hartford and State of Connecticut,have invented certain new and useful Improvements in Tinsmiths Beading Machines, of .which the following is a speci ication.

My invention relates to improvements in tinsmiths beading-machines; and the object of my invention is to provide an attachable and detachable rest for supporting a tube of considerable length when it is desired to bead.

the same. i l

In the accompanying drawings, Figure 1 is a side elevation of a known beading-machine with my improvement attached thereto. Fig. 21s a longitudinal section of my attachable and detachable rest, together with the lower beading-roller and a portion of the lower shaft. Fig. 3 shows, respectively, a sectional View and side elevation of the nut for securing the beading-roller in place when the rest is removed. Fig. 4 is a Vview corresponding to Fig. 2, showing a modified construction; and Fig. 5 represents a sectional and side View of the cap-screw for holding the beading-roller when the rest is removed.

The heading-machine represented in Fig. 1 is made in accordance with' my Letters Patent No. 356,897, February n1, 1887; but my present improvement is applicable to other known forms of beading-machines.v

A designates the lower beadingrolle1,fitted upon the shaft end, `with its end abutting against the collar a on said shaft in the usual manner. At the fronty end of the roller the projecting shaft end b, Fig. 2, is screw-threaded, to receive the ordinaryholding-nut, Fig. 3, for securing the roller in place. Whenthis nut is upon the shaft end, the machine is in its ordinary condition, and may be used in t-he ordinary manner. For short work it will be most convenient to use the machine in this condition.

When itis desired to form a bead upon a tube or vessel that projects some distance beyond the point to'be beaded, it is desirable to nut, Fig. 3, and screwing upon the shaft and have an internal rest forsupporting the work.`

This I accomplishby removing the ordinary 5c.;V g,

up against the end of the beading-roller the f rest-rod B, said rod having, in the form shown in Figs. 1 and 2, a ange, c, the periphery of .A

which is'angular, for the application of a wrench. At the end of said rod is a central bore, which is threaded to matchl the thread g on the end b of the shaft.4 The side .face

of the iiange issquared andV presses against the outer end ofthe roller "A, and thereby holds the .roller ,inl place, the same asdoes the nut, Fig. 3. On this rest-rod B, I forma 'I the rest C, Lwhichis bored outto iit the rest; rod, upon which it slides, and is provided with a vset-screw, d, forholdingit in'its ad-` justed position upon the. rod. A cylinder or vessel' may be supported on this restfwhilel forming the bead, and kit will revolve with the beading-rollers without being driven hand.

The construction shown in Figs. 4 and 5-is substantially the saine. as that before described,

except that the `threads arev inverted-that is A to say, the threaded interior is formed on the shaft end, while the exteriorly-threaded portion e is `formed ori the guide-rod B. A fiange,

f, having an angular periphery for the application of a wrench, has one side squarediup to@y form the shoulder for bearing against the outer i end of the roller. f f

Vhen it is desired to use the machine without the rest, the rest-.rod is unscrewed and the i I cap-screw, Fig. v5, in the modification shown in Fig.y 4,' or a nut, Fig. 3, in the construction f In both.

shown in Figs. 1 and 2,- is substituted forthe rest-rod, to hold the roller in place. constructions the lower shaft is provided with a thread ed end, while the'rest-rod has a screwthredd which is fated to the threaded end" of Y y 90y .i

said lower shaft.

By this construction the restis not onlyv conveniently attached and detached, but it is attached in such manner as to run true, and' to practically form a continuation of the lowerf shaft, and it may be madey of anyjdesired '951;

length; or, if required, two o'r more rest-rods 2 avvflvo of different lengths may be furnished for one machine.

I claim as my invention- In a. beading-machine, the combination of y 5 the'lower shaft, having a threaded end, and" Vitnesses:

roller, with the rest G and rest-rod B, having STEPHEN WALKLEY,

adapted to be attached and detached from said shaft and roller, substantially as described, and for the purpose specified.
